WINDOW STRUCTURE Filed April 27. 1967 2 Sheets-Sheet 2 FIGG INVENTOR. RICHARD N. ANDERSQN M7 ATTORNEYS United States Patent 3,464,160 WINDOW STRUCTURE Richard N. Anderson, Miami, Fla., assignor to V. E. Anderson Mfg. Co., Owensboro, Ky., a corporation of Kentucky Filed Apr. 27, 1967, Ser. No. 634,169 Int. Cl. E0511 /22, 15/18 US. Cl. 49181 11 Claims ABSTRACT OF THE DISCLOSURE Tilting double hung window construction including a single plastic guide member at each side of a window sash for providing compression between a window frame and the window sash mounted therein and Weatherstripping therebetween as well as guiding the window sash in sliding movement relative to the frame and camming locking structure for securing the window sash in a vertical position, especially in conjunction with counterbalance structure which is readily engageable with and releasable from the counterbalance structure.

Background of the invention In the past tilting double hung windows of the type which may be cleaned from the inside of a building in which the window is installed by pivoting the window sash about one edge thereof to expose the outside surface for cleaning have been deficient in that the usual means for supporting the sash in the window frames have been rather complicated, often expensive and sometimes inefficient. Thus, a minimum of three separate members, that is a metal guide for the sash, spring means operable between the metal guide and window frame for maintaining compression of the metal guide against the sash and a felt member or similar Weatherstrip material between the sash and outer frame have usually been required at each side of the window sash.

Wherein, locking structure has been provided in the past to maintain the sash of tilting double hung windows L in a predetermined vertical position when tilted, the locking structure has been complicated, expensive to manufacture or inefficient. Further the prior locking structures have not generally been readily engageable with and releasable from assembly with counterbalance structure for the sash.

In addition prior window structures have generally been either metal or wood. That is, if a metal exterior has been required in the past for maintenance purposes the interior of previous window structures has generally also been metal. Conversely, when a wooden window has been desired for aesthetic appearance and warmth the entire window has usually been constructed of wood in the past. The interior aesthetic appearance and warmth of wood has not previously been satisfactorily combined with the maintenance advantages of metal exterior structure.

Summary of the invention It is therefore an object of the present invention to provide improved window structure.

Another object is to provide double hung window structure utilizing a minimum number of separate parts.

Another object is to provide window structure as set forth above including a single member at each side of the window structure for guiding window sash, providing a compressive force on the sash and weatherproofing the space between the window frame and sash.

Another object is to provide window structure as set forth above and including locking means for securing the window sash in a vertical position relative to the frame on tilting of the sash in the frame.

Another object is to provide window structure as set forth above including counterbalance structure and locking means as set forth above which locking means is readily engageable with and disengageable from the counterbalance structure.

Another object is to provide window structure as set forth above which has an exterior aluminum frame and which is wooden in interior appearance.

Another object is to provide window structure as set forth above which is simple in construction, economical to manufacture and efiicient in use.

Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, illustrating a preferred embodiment of the invention.

FIGURES 6 and 7 are enlarged partial section views of the locking structure illustrated in FIGURE 5 taken substantially on the line 6-6 in FIGURE 5 and showing the sash in a closed and tilted position, respectively.

Description of the preferred embodiments The window structure 10 of the invention includes a window frame 12, a pair of window sash 14 and 16 and guide members 18 and 20. The frame 12 is metal, the sash 14 and 16 are wood, and the guide members 18 and 20 are plastic.

The frame, sash and guide members when assembled as illustrated in FIGURES 3 and 4, provide a tilting double hung window, the sash of which may be pivoted inwardly for cleaning or for subsequent tilting and removing as desired. In addition, as shown best in FIGURES 3 and 4, the window construction 10 combines the advantages of a metal exterior and a wood interior, so that maintenance is kept to a minimum and the natural beauty of wood is preserved.

More specifically, the frame 12 includes the head member 22, the jamb members 24 and 26 and the sill member 28. The head and jamb members have a single cross section as illustrated including a mounting flange 30 to aid in installation of the window structure 10 in a building opening, an exterior molding portion 32 and portions 34, 36, 38 and 40 forming pockets 42 and 44 for receiving the guide members 18 and 20.

The sill member 28 includes the outwardly and downwardly inclined portion 46 and the portion 48 for securing the sill in a building opening. A water-stop portion 50 is provided on the cross section of the sill 28 at the outside thereof and a molding receiving portion and sash stop member 52 is provided on the inside of the sill member 28. The head, jamb and sill members 22, 24, 26 and 28 as shown may be mitered and connected by convenient corner structure (not shown).

clude head, jamb and sill members 54, 56, 58 and 60. The head, jamb and sill members are provided with recesses 62 in which glass panes or other building panels 64 are secured by means of the resilient metal clips 66. At the bottom of both the sash member 14 and the sash member 16, as shown in FIGURE 3, pivot pins 68 are provided on each side to permit pivoting of the windows thereabout. The sash 14 and 16 are guided in vertical movement by means of the edge portions 80 and 82 thereof extending into the guide members 18 and 20, as shown best in FIGURE 4. A finger gripping recess 70 is provided in the sill of the lower sash 14 which becomes the head of the upper sash 16, as shown best in FIGURE 3. Thus, opening and closing of the sash 14 and 16 is facilitated.

The guide members 18 and 20 are constructed of a resilient plastic, such as a semi-rigid vinyl, nylon or the like. The guide members have a cross section illustrated best in FIGURE 4 including a pair of recesses 72 and 74 for receiving the pivot pins 68 on the sash 14 and 16. The members 18 and 20 are further provided with lesser recesses 76 and 78 for receiving the edge portions 80 and 82 at the sides of the sash 14 and 16, whereby the sash are guided in vertical movement within the frame 12, as previously indicated.

The arcuate resilient portions 84, 86 and 88 of the guide members 18 and 20 extend into the pockets 42 and 44 as shown and tend to urge the members 18 and 20 out of the pockets 42 and 44 and into engagement with the jambs of the sash 14 and 16. The direction in which the arcuate portions 84, 86 and 88 are bent and the resiliency thereof provided weathertight window structure between the frame 12 and sash 14 and 16.

The frame portions 36 and 38 are provided with projections 90 and 92 extending into the pocket 42 which mate with abutments 94 and 96 on the portions 84 and 86 of the guide members 18 and 20 to maintain the guide members 18 and 20 within the pockets 42 and 44. Similar projections can be provided on the portion 40 of the frame jambs 24 and 26 on the portions 88 of the guide members 18 and 20 if desired.

Locking structure 98 is provided operable between the sash 14 and 16 in the closed position and Weatherstripping 100 and 102 is provided as desired to provide a weathertight window.

Window structure is completed by the wood interior molding 104 secured over the portions 40 and 52 of the head, jamb and sill members 22, 24, 26 and 28, as shown in FIGURES 3 and 4.

In overall operation with the locking structure 98 unlocked, the inner sash 14 may be grasped by the head and pulled inwardly to pivot about the pivot pins 68 at the bottom thereof on forcing of the portion of the guide members 18 and supported primarily by the portions 88 inwardly of the pockets 44. Thus, either surface of the window pane 64 may be exposed on the inside of the window structure 10 for cleaning or the like, as shown in FIGURE 2. On lowering the upper sash 16 the head of the upper sash 16 may then be gripped and the upper sash pivoted about the pivot pins 68 adjacent the bottom thereof to urge the portion of the guide members 18 and 20 supported primarily by portions 84 and 86 into the pockets 42. Again then both surfaces of the window pane in the upper sash 16 may be exposed for cleaning or the like on the inside of the window structure 10.

With the windows in the tilted position, as shown in FIGURE 2, they may be further inclined so that one side is raised higher than the other whereby the pivot pins 68 may be removed from the recesses 74 and 72 and the sash 14 and 16 completely removed from the window structure 10 for replacing, repairing or the like.

Conversely, when it is desired to close the window 4 structure 10, the sash are first placed in the frame 12 with the pivot pins 68 in the recesses 74 or 72 to provide a horizontal pivot axis for the sash and the sash is then pivoted back into the vertical position with the guide ortions and 82 of the sash within the recess 76 or 78 of the guide members 18 and 20.

The lower sash may then be moved all the way to the bottom, as illustrated in FIGURE 3, the upper sash may be moved all the way to the top and the locking structure 98 latched whereby the bottom of the lower sash is secured due to the pivot pins 68. The top of the lower sash and the bottom of the upper sash are secured due to the pivot pins adjacent the bottom of the upper sash and the latch structure 98 and the head of the upper sash 16 is secured due to the placing of the head of the sash in the pocket42 in the head member 22.

The window structure 10, illustrated in FIGURES 1-4, includes no counterbalance structure since the resilience of the guide members 18 and 20 is such as to firmly hold the sash 14 and 16 in any adjusted vertical position without requiring undue effort to move the sash from one adjusted position to another. Where sash may be larger or heavier, due for example to glazing with dual panes of glass for thermal insulation and the like, counterbalance structure 108 as shown in FIGURES 5-7 may be provided.

The counterbalance structure 108 is the same on both sides of the window structure and includes a coil spring 110, the opposite ends of which are provided with hooks 112 and 114 which are secured over the top of a guide member 18 or 20 and to a shoe 116, respectively. The shoe 116 is constructed to permit ready engagement of the counterbalance structure with a pivot pin 118 and disassembly of the counterbalance structure and pivot pin 118.

Thus, the shoes 116 include a cylindrical portion 120 extending transversely thereof with which the hook 114 is engaged and an elongated opening 122 therein for receiving the end 126 of the pivot pin 118, as shown best.

in FIGURES 6 and 7. A camming surface 124 is provided on the shoe 116 to facilitate engagement of the pivot pin 118 in the opening 122. The end portion 126 of pivot pin 118 is eccentric and fits within the opening 122 with the shoe 116 in assembly with the pivot pin 118.

Thus, in operation of the window structure 10 having the counterbalance structure 108, as illustrated in FIGURES 5-7, and with the end 126 of pivot pin 118 in the opening 122 in shoe 116, when the sash 14 is moved vertically in a non-tilted position, as shown in FIGURE 6, the shoe 116 is guided along the recess 74 in the guide member 18. When the sash 14 is tilted, as shown in FIGURE 7, the eccentric end 126 on the pivot pin 118 will cam the shoe 116 against one side of the recess 74 to secure the sash 14 in a vertical position relative to the window frame 12. The camming action is illustrated in FIGURE 7. Without the camming action provided by the shoe 116 and eccentric end 126 on the pivot pin 118 the counterbalance structure 108 would have a tendency to pull the side of the sash 14 upward when the sash is tilted in the lower position, as shown in FIGURE 2.

It will be readily understood that the window sash 14 may still be removed on spreading of the guide members 18 and 20 to remove the end 126 of the pivot pin 118 from the shoe 116. With the sash removed the counterbalance structure 108 will return the shoe 116 to an upper position. The pin 118 may then be reengaged with the shoe 116 on reinserting the sash in the window frame 12 with the pivot pin 118 extending into the recess 74 and moving the sash vertically up to cam the eccentric end portion 126 of the pivot pin along the surface 124, after which it extends into the opening 122.

Thus, it will be seen that there is provided in accordance with the invention a double hung tilting window which is particularly simple, economical and efficient. Further, it will be noted that the window structure 10 includes a minimum number of separte parts to provide the sash guiding function, a resilient guiding member and Weatherstripping in such a window. Also, it will be noted that from the inside the window will appear to be a wooden window, while from the outside the metal frame will require a minimum amount of maintenance.

While one embodiment and a modification of the present invention have been disclosed in detail, it will be understood that other embodiments and modifications thereof are contemplated. Thus, while the invention has been disclosed in conjunction with a tilting double hung window, it will be evident that the structure can be used for horizontal sliding windows and the like. Also, it will be readily understood that other counterbalance structure and locking means may be used in conjunction with the window structure to assist in raising and lowering the sash and securing them in a vertical position on tilting. It is the intention to include all embodiments and modifications within the scope of the invention.
